T 0 all whom 'it may concern.'

Be it known that I, THOMAS S. HoMANs,

a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Typographical Machines, of which the following is a specification.

The present invention relates` to improvements in typographical machines and more particularly to those of the linotype class substantially as shown and described in U. S. Letters Patent to O. Mergenthaler, No. 436,532, granted September 16, 1890.

Typographical machines of the kind referred to have.heretofore been constructed generally to produce type bars or slugs having a maximum length of five inches and while many attempts have been made to substantially increase the length of type bars obtainable from such machines and to thus increase the efficiency and broaden the range of use of the machine, such attempts have been unsuccessful, although developments have been made with this object in view which enabled type bars or slugs to be obtained which were about one inch longer than thdse usually obtainable, but which did not materially increase the range of use of the machine.

The primary object of the present invention is to provide certain improvements which substantially increase the efficiency and broaden the range of use of typographical machines of tlielinotype class by enabling such machines to produce type bars or slugs having a length' of seven inches or a length' equivalent to 42 ems, these improvements enabling 'machines of the 1 linotype class to accomplish this result without re-` quiring changes in the machine other than those necessary to increase the capacity of the assembling and distributing mechanisms to accommodate the increased length ofthe lines. fThe improvements which enable these results -to be attained, pertain to the means which transfers the lines of matrices of increased length from the so-called first elevator to the so-called second elevator and A the casting mechanism which according to the present .invention has an increased capacity which enables it to successfully cast the type bars or slugs of increased length from 'the lines of matrices, the casting mechanism in its preferred embodiment being provided with means to control its capacity whereby it may cast type bars or slugs of the usual or shorter lengths, as well as those of increased length.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as Wlll be hereinafter more fully described, the features of novelty being pointed out particularly in the claims 'at the end of the specification. i

In the accompanying drawings Figure 1 is a front elevation of that portion of a machine of the linotype class which effects the transfer ofthe line of matrices vfrom the first elevator tothe second elevator, the line transfer means, as shown, being in accordance with the present inventlon;

Figure 2 is .a detail perspective view of the line transfer means shown in Figure 1; Figure 3 represents a transverse section through the line transfer means shown in Fi ures1and2; ,i

igure 4 Ais a perspective view of casting mechanism constructed in'accordance with the present invention; and

Figure 5 is a top plan view of the metal pot illustrating how a cast may be ymade from a relatively short line of matrices.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicable generally to line casting machines of the -kind wherein the line of matrices from which the type bar or .slug is to be cast is presented to the casting mechanism by an elevator or similar means, and after the cast has been, made the line of matrices is transferred from such elevator to another or second'elevator or equivalent meanslwhic'hconveys the matrices to matrix-distributing.mechanism by which the matrices composing the line are returned to their respective cells or channels in a matrix storage magazine. The invention` isA particularly -applicable to typographical machines of the linotype class, as 1s shown and described substantially in the Mergenthaler patent hereinbefore referredto, and the invention is so illustrated in the accompanying drawings and will be hereinafter described. It -is to be understood m inea-rea l of matrices from the usual first elevator,

afterv a cast has been made therefrom, to the second elevator which conveys the line of matrices to the distributor, 2 desigating the upper portion ofthe second elevator in position to receive the line of matrices M endwise from the channel in the first elevator, it being understood that the line of matrices is elevated to the transfer pointer to the level occupied by the second. elevator 2 by the usual upward movement of the first elevator following the casting operation. The transfer of the line from the first to'the second elevator is usually effected by a line transfer carriage 3 which slides or reciproeates in a relatively hired guide t, the carriage carrying a linger 5 which is adapted tooccupy a position beyond the left-hand end of the .line when the line is'brought to the transfer level, as is shown in Figure 1, following lwhich the line transfer carriage and 'with it the dinger 5 are shifted toward the right in Figure l, the finger 5 thus coming against the end of the line and shifting the latter endwise onto the second elevator 2. 'lhe line transfer carriage in machines of the linotype class is reciprocated at appropriate intervals and through a predetermined stroke-by an arm or lever 6 which has a dried throw and is usually actuated by a cam on the main or cam shaft of the machine.

lt is usual in machines of the linotype class to,

connect the arm or lever 6 to the line transfer carriage directly by a connecting link or pitman.

ln order` to accommodate the line transfer .mechanism to handle lines of matrices of reatly increased length, as is contemplated y the present invention, it became necessary to increase the length of stroke of the line transfercarriage and in order to obtain this result within the limited space available and to thus avoid reconstruction of this part of the machine, `it became necessary to devise means to increase the length of stroke of the line transfer carriage without altering the timing and which means is compact so that it will perform its function and.

` yet avoid interference with other adjacent parts of the machinec Preferably and as show-n in the present instance, such means comprises a toothed rack '7 which is fixed to' the adjacent stationary part 1 of the machine in vpenallelisin with and below the line of travel of the line transfer carriage 3, a toothed rack 8 which is fixed-to or carried by the line transfer carriage and is parallel to but offset forwardly relatively to the stationary rack 7, and a rolling or shifting gear member comprising a gear 9 which meshes with and traverses the stationary rack 7 and a gea-r 10 of proportionately smaller diameter which meshes with and traverses the vthe latter being operatively connected tol the usual actuating arm or crank 6. Preferably, a'cfircular disk 13 is fixed to one side of the gear 9, the periphery of this disk coinciding with the pitch line of this gear and a cooperative rail 14 isxed at one side of the rack 7, the upper edge of the rail being on the level with the pitch line of the rack. By this arrangement, the disk 13 and rail la 80 will support the gearelement during its toand-fro movements under the action of the arm 6 and link 12 and will prevent bottoming of the teeth of the gear 9 and rack 7. A guard 15 is preferably applied to the for- 85 ward side of the rack 7 and rail lt, this guard protecting the rack and its cooperating gear and also serving as a guide for the forward side of the disk 13, the rear side of this disk being engaged and guided by the teeth of the rack 7 which project above its upper edge. The rack 8 attached to the line transfer carriage may, as shown, be formed by an overhang from ysuch carriage, the overhang being preferably utilized as a guard which encleses ,and accommodates the'tops of the gear 9 and the disk 13.

lt is to be understood that the ratio between the diameters of the gears 9 and 10 is such that the range of stroke obtained by the usual line transfer operating 'arm or crank 6 is-multiplied or increased as it is transmitted to the line transfer carriage, and hence the length of stroke of the line transfer carriage will be increased to the extent necessary to enable it 'to receive the line of matrices of increased length in front of the finger 5 and to shift through a range sulficient to completely transfer such line of matrices from the first elevator to the sec- 11e ond elevator. 'llhe' construction described en ables this result to be attained without disturbing theactuating arm or crank 6 or its cam and, moreover, the mechanism is compact and is easily accommodated within the limited space available in rear of the-first elevator, when the latter is raised to its upper or line discharging position. l rllhe casting mechanism commonly employed in line casting machines of the lino-l type class embody a mold and metal pot which are constructed to produceitype bars or slugs of relatively short length only, five inches being the limit of length heretofore used generally.'y 'llhe present invention pro- 125 vides casting mechanism which is capable of casting type bars or slugs of the substantially increased length and in its preferredf construction it is capable of'being easily and quickly adjusted to cast either the relatively 13a sol long type bars or slugs or the relatively shorter length commonly used. As shown in the present instance, 16 represents the mold Whichfmay be of the type generally used in machines of this class, it being understood that the length of the mold cavity is set or adjusted according to the: length of the type bar or slug to be produced. In Figure' 5 a line of matrices M of the usual length is shown presented to one side of the mold, the line ofI matrices being clamped or locked betweentheusual vise jaws 17, andthe metal pot 18 is presented to the opposite side of the mold and operates in af manner to be hereinafter described to .cast the type bar in the mold. According to the present invention, the mouth piece 19 of the metal pot, 'which mouth piece, is adapted to fit against the line ofmatrices from which the cast is to be made is increased in width to conform with the increased length of the lines of matrices which may be presented thereto for the casting of type bars' or slugs of the increased length, themouth-piece having preferably a row of suitably spaced openings 2O through which the metal is injected into the mold cavity and these openings in the mouth-piece are supplied with molten type met-al by a pair of throats 21v and 22 which, as shown 1n Figure 5, 'are-outof communication with one another; in

other words, they independently supply type metal to respective portions of the mouthpiece. The throats 21 and 22 lead froml individual pump wells 23 and 24 which'may receive metal in the. usual way from the main mdlten metal well 25 of the pot and they are fitted with individual pump plungers which are connected respectivel to the plunger rods 26 and 27, it beingun erstood that 1n line casting machines of the linotype class each downward stroke ofv the plunger of the metal pot serves of molten type metal through Athe mouthpiece of the metal pot into the mold to makethe cast therein, although the metal potscommonly used in machines of the 'linotype .class employed one plunger only, whereas,

according to the present invention, two plungers are provided which supply type metal to different portions of the mouthpiece. I have found from experience that this dquble means fondelivering metal to the-mouth-.piece is necessary, in order to enable the same casting mechanism to successfully cast eitherthe long type bars or type bars of the relatively short lengths as commonly used, because if a single/metal delivery means were provided for a mouthpiece designed ,to 'cast the relatively long type bars and it were attempted to use the same metal injecting means in the casting oftype bars of the relatively shorter lengths, the Qmetal delivered from a well and plunger,v adapted Vto the casting of long lines yorout of operation according to the to inject asupplywould leak between the mouth-piece and the matrices and vise jaws, due to the excess metal that would be injected, and this leak- .and -the objections which presented themselveswere overcome. The present invention provides means whereby the casting mechanism may be quickly and easily set for the casting of either the longer or shorter lines, it embodying preferably means for setting one lof the plungers either into of line being handled by the machine, thus enabling the casting mechanism to operate with equal facility, irrespective of the length of'line being handled. As shown in Figure 4, the metal injecting plungers 26 and 27 are operatively connected to levers length 28 and 29 which latter are pivoted at 30 to a stationary part 31 of the frame ofthe machine, and springs 32 and 33 act on the respectivel levers to force the plungers connected thereto downwardly to perform a metal-injecting operation. @ne of the levers, the lever 28 in thepresent instance,

carries a roller 34 which travels on a cam 35, this plunger-actuating mechanism shown l in the present instance corresponding substantially with that fully. shown and described in U. S. Letters Patent No.' 1,108,804,.-

granted August 25, '1914, it being -understood that a metal-injectlng operation occurs at the proper period durin each cyclev ldy the conconnected 'l of operations ofthe machine. struction described, the plunger to the lever 28 willperform a metal-injecting operation during each operation of the cam 35. Means is provided by which the other plunger connected to the lever 29 may be either set to operate in unison with the first-mentioned. plunger, or it may be restrained from operation or otherwise ren-` Preferably a'nd as shown, the lever 28 is provided with a step or lug dered inoperative.

36 arrangedl below the lever 29, and this lever 29 may reston this step or lug, in which case itwil operate funder the actionof its spring 33in unison'with the other plunger, and hence metal. will be plungers through the metal pot mouth-piece, this eing the operation whenthe` relatively long type bars are beingv produced.- Suitable means is provided for restraining or preventing operation of the plunger con-I nected to the plunger bar 27 so that one plunger only vwill operate during the projection of the relatively short type bars. As

shown in the present instance, a hook 37 is injected by both pivotally hung from a pin 38 and the lever 29 has a pin 39 fixed thereto. the hook 3T being adapted lto engage beneath the pin 39 when the leveinQS) is elevated and to thus restrain operation of the plunger' connected to this lever. Suitable means is provided for setting or controlling the hook 37, a bar 40 being operatively connected to it in the present instance, this bar extending toward the front of the machine where it is provided with a suitable handle-41 and by push ing the bar 40 rearwardly the hook 3T will clear the pin 39 so that the plunger attached to the lever 29 may operate in unison with the plunger attached to the lever 2S, whereby Ypulling the bar al() forwardly after the lever 29 has been elevated by the. cam 85, the hook 37 will engage beneath the pin 39 and will lock the leverQS) in elevated position and thereby preventing operation of the plunger attached to this lever. Any suitable means may be employed for holding the bar 40 in either of its two positions, a relativeljv lfiiied pin or projection i2 being provided in the present instance which is adapted to engage either one of the two notches 43 formed in the bar 40, these notches corresponding to the forward and rearward positions of the bar.

By constructing the casting mechanism as described, the proper quantity of molten type metalwill be injected into the mold to fill it, when the relatively long type bars are being produced, owing to the conjoint operation of both metal-injecting plungers,

and when relatively short type bars are being cast, the correspondingly short matrix lines M and mold cavity are presented at one side of the metal pot mouth-piece, substantially as is illustrated in Figure 5, the relativly short mold cavity receiving the proper amount of molten type metal from one plunger through the single throat 2l Which is divided 0E from the companion throat 32 throughout its length and as far as the discharge side of the mouth-piece, and hence escape of molten metal beyond the end of the line of matrices is avoided.
